Title: Lifting electromagnet device
Inventor: SAKAE NOBUSHIGE
IPC: B66C1/08
Filed: 1988-03-14
Abstract: PURPOSE:To prevent the generation of a failure in lifting and oscillation of objects to be lifted in the lifting electromagnet device for attracting and transporting steel sheets, etc., by arranging a lifting electromagnet device not to be excited unless the attracting surface of an electromagnet is horizontal or near the horizontal. CONSTITUTION:Lifting electromagnets 4, 5 are respectively hanged on hooks 2, 3 of a lifting beam 1. Mercury switches 8, 9 do not operate when the attracting surfaces of the lifting electromagnets 4, 5 are within a specified range of angle against the horizontal, and they operate when the attracting surfaces are out of the specified range of angle. Accordingly, when both inclinations of the lifting electromagnets 4, 5 are within the specified range of angle, both contacts (b) of the mercury switches 8, 9 remain closed, so that a relay is excited to close the contacts (a), and the exciting operations of the lifting electromagnets 4, 5 are performed by an exciting circuit. On the other hand, when the inclination of at least one of the lifting electromagnets 4, 5 exceeds the specified angle, the exciting operations of the lifting electromagnets 4, 5 by means of the exciting circuit are prohibited.

Title: Facsimile terminal equipment
Inventor: NAKAJIMA HIDEO
IPC: H04N1/00
Filed: 1985-03-26
Abstract: PURPOSE:To reduce useless transmission due to mis-setting and thereby to improve the operability and the usage efficiency of the line by executing a preliminary scanning to confirm front/rear page of the original set in the reading part prior to the transmission. CONSTITUTION:After a CPU 61 detects the setting of the original on the table for original, the original is scanned preliminary with a scanning-line density of 2 lines/mm lower than that used in transmission of, for instance, 8 lines/mm. At this time, the AND gate 72 of a changeover circuit 15 on the side of a binarizing circuit 15 is open while the AND gate 71 is closed. If the original is normally set, some a recording information is detected by the said preliminary scanning, by which the CPU 61 decides that the state of setting of the original is normal, stops the preliminary scanning, and lets the transmission scanning of normal operation be executed. In case no recording information is detected, the CPU decides that the setting of the original is errored, and displayed it in a displayer part 9.

IPC: B22D11/06
Filed: 1993-03-22
Abstract: PURPOSE:To reduce the deviation of a strip thickness caused by the thermal deformation of nozzle opening and to eable stable casting in a long term by forming the passage in the nozzle guiding a molten metal to the nozzle opening to be narrow at the inlet side and wide at the outlet side. CONSTITUTION:The molten metal is charged into a tundish 1 from a supplying nozzle 2 and the pouring nozzle 4 is arranged at the bottom part of the tundish. Then the molten metal is jetted on a cooling roll 5 arranged just below the pouring nozzle 4 from a slit-like opening of the pouring nozzle 4 and forcedly and rapidly solidified to produce the strip 6. The passage 10 in the pouring nozzle 4 guiding the molten metal 3 into the tundish 1 from a molten metal basin part 8 to the opening 9 is made to be narrow at the inlet zone 11 and wide at the outlet zone 12. Therefore, because the flowing pressure loss at the inlet zone 11 can be made large, the uniform low rate distribution in the width direction is obtd. Further, because the nozzle opening is wider than the ordinary nozzle, the thermal margin heat loss at the nozzle tip is large and the generation of nozzle clogging can be avoided.
